The ones on the top shelves hold show hats, show boots, and tack we are not using right now or do not use often. The stack of bins on the shelves holds combs, brushes, bathing stuff, tools and misc.
I better add a disclaimer here. First of all most of my tack we bought from a big farm that was going out of business. Very few things did I buy one at a time. It was all in a storage shed and we paid one lump sum. Second I am very fortunate to have a builder for a husband. We bought the lumber unfinished very reasonable at a saw mill. My husband built all the shelves, hooks and hangers. I then put a coat of polyurethane on everything. The cabinets we got basically for free, they were a floor model and our building supplier threw them in because we bought another larger floor model set.We had to reconfigure them to make them work but I think it looks ok. My darling daughter is supposed to be making a curtain for the window and one to cover the plumbing stuff.
It has taken us years to get our barn to this almost finished state. All things take time and money to complete and we rarely seem to have both at the same time.
